Description

CROSS-REFERENCE TO RELATED APPLICATION

Benefit is claimed of U.S. Patent application No. 62/263,055, filed Dec. 4, 2015, and entitled “Security System With Fixture And Tracking Devices For In Room Security Of Valuables”, the disclosure of which is incorporated by reference herein in its entirety as if set forth at length.

BACKGROUND

The present disclosure relates to a security system and, more particularly, to a security system that pairs an fixture and one or more tracking devices.

An access control system is typically operated by encoding data on a physical key card that indicates access rights. Some access control systems are offline and the access rights are encoded as data that can be decoded and interpreted by the offline lock to retrieve the access rights. An example is a hotel locking system where a front desk encodes a guest card and an offline, battery powered lock on a guest room door has the means to decode the card and permit or deny access based on the encoded access rights.

Although effective to control access to a local such as a hotel room, it has been noticed that valuables of the guest can be readily removed from the local once access is gained. Although effective, hotel staff and maintenance have access to the guest rooms and enter the room for miscellaneous purposes regardless of the lock.

It should be appreciated, however, the following description and drawings are intended to be exemplary in nature and non-limiting.

BRIEF DESCRIPTION OF THE DRAWINGS

Various features will become apparent to those skilled in the art from the following detailed description of the disclosed non-limiting embodiment. The drawings that accompany the detailed description can be briefly described as follows:

FIG. 1 is a schematic view of a security system according to one disclosed non-limiting embodiment;

FIG. 2 is a block diagram of the security system; and

FIG. 3 is a block diagram for an operational use case of the security system according to one disclosed non-limiting embodiment.

DETAILED DESCRIPTION

FIG. 1 schematically illustrates a security system 10. The security system 10 generally includes a fixture 12 and one or more tracking devices 14 attached to the valuable. It should be appreciated that the fixture 12 may be a wireless-capable, restricted-access, or restricted-use device such as a wireless lock, a security panel, access control readers for building entry, electronic banking controls, data transfer devices, key dispenser devices, tool dispensing devices, and other restricted-use machines. Alternatively, the fixture 12 may be another type of device that is fixed in location such as a thermostat.

A user may submit a credential to an electromechanical lock to unlock it, and thereby gain access to a restricted area. In another example, a user may submit a credential to an electronic banking control such as an ATM to withdraw funds. In still another example, the user may submit the credential to a unit that dispenses key cards with data associated with or data retrieved from the credential. A mobile device 16 such as a key card, smartphone, or other device may store credentials for one or all or other of the examples noted above, and in addition may store a plurality of credentials for each type of application at the same time.

It should be still further appreciated that although particular systems are separately defined, each or any of the systems may be otherwise combined or separated via hardware and/or software. The communication may be conveyed to one or more networks. For example, the communication may be transmitted to the Internet and/or a cellular network. The network(s) may include infrastructure that may be organized to facilitate cloud computing. For example, cloud computing may include one or more servers, such as a primary message server, a backup message server, etc.

With reference to FIG. 2, a block diagram of the fixture 12 is schematically illustrated. In this example, the fixture 12 is depicted as an electromechanical lock system, however, other fixtures will benefit herefrom. A “fixture” as utilized is a device that is affixed to a building or other structure.

The fixture 12 generally includes a lock actuator 22, a lock controller 24, a lock antenna 26, a lock transceiver 28, a lock processor 30, a lock memory 32, a lock power supply 34, a lock card reader 90 and a credential module 36. The fixture 12 is responsive to credentials from a keycard or other mobile device 16, and may, for example, be the lock of a lockbox, a door lock, or a lock core. Upon receiving and authenticating an appropriate credential, the lock controller 24 commands the lock actuator 22 to lock or unlock a mechanical or electromechanical lock. The lock controller 24 and the lock actuator 22 may be parts of a single electronic or electromechanical lock unit, or may be components sold or installed separately.

The lock transceiver 28 is operable to transmit and receive data to and from at least the mobile device 16. The lock transceiver 28 may, for instance, utilize a near field communication (NFC), Bluetooth, or Wi-Fi transceiver, or another appropriate wireless transceiver. The lock antenna 26 is any antenna appropriate to the lock transceiver 28. The lock processor 30 and lock memory 32 are, respectively, data processing, and storage devices. The lock processor 30 may, for instance, be a microprocessor that can process instructions to validate card data and determine the access rights contained in the card data or to pass messages from a transceiver to a credential module 36 and to receive a response indication back from the credential module 36 with card data. The lock memory 32 may be RAM, EEPROM, or other storage medium where the lock processor 30 can read and write data including but not limited to lock configuration options and the lock audit trail. The lock audit trail may be a unified audit trail that includes events initiated by accessing the lock via the lock card reader 90 or the mobile device 16. The lock power supply 34 is a power source such as line power connection, a power scavenging system, or a battery that powers the lock controller 24. In other embodiments, the lock power supply 34 may only power the lock controller 24, with the lock actuator 22 powered primarily or entirely by another source, such as user work (e.g. turning a bolt).

The lock transceiver 28 is also operable to communicate with the tracking devices 14. The tracking devices 14 may be initially paired to the lock transceiver 28, via, for example, a ‘learn’ mode for learning a tracking device and associating therewith. Alternatively, or in addition, this may be based on proximity—i.e. the lock transceiver 28 will respond to a tracking device based on distance. The communication can include any wireless ISM band and protocol to include, for example, Bluetooth Low energy wireless protocol. The tracking device 14 may be of various configurations such as a hook and loop strap, a bankcard, sticking materials, a user's mobile device, and various tags that lock to an item.(valuable)

Each tracking device 14 may generally include a control module 40 with a processor 42, a memory 44, and an interface 46. A power supply 48, such as a battery, and a position module 50 operable to determine the position of the tracking device 14, and transceiver module 52 are in communication with the processor 42 via the interface 46. The position module 50 is operable to determine movement of the tracking device 14. For example, the position module 50 may include an accelerometer 50A to identify movement, a global positioning system (GPS) 50B, and/or a triangulation system 50C that determines the position of the tracking device 14 with respect to the fixture 12 based, for example, on a signal strength thereof. Alternatively, or in addition, the position module 50 may include a light sensor 50D to identify when a bag is opened and luminous would change for a tracking device 14 located within a bag

With reference to FIG. 3, a method 100 for operation of the security system 10 is disclosed in terms of functional block diagrams. It should be appreciated that these functions may be enacted in either dedicated hardware circuitry or programmed software routines capable of execution in various microprocessor based electronics control embodiments.

Initially, a guest physically attaches a tracking device 14 to his valuable (e.g. luggage) (step 110) using for example a loop strap. Then fixture and tracking device are wirelessly attached by getting them paired and putting them into learning mode. These modes can be achieved by sequencing and timing the push buttons in tracking device and the fixture. Once pairing mode and learning mode is complete even when the authorized guest is in the room, the tracking device 14 is inoperative or in a safe condition.

Next, when the guest leaves the room, the guest arms the wirelessly connected tracking device 14 (step 120) by, for example, pushing a button on the fixture 12, e.g., the electromechanical lock, via a mobile app on a smartphone, or other interface. This arming may be effectuated via an authentication procedure. For example, arm the tracking device, a mobile device may be used to authenticate the fixture 12 with a credential and also supply a command to ‘arm’ the tracking devices 14. It should be appreciated that multiple tracking devices 14 may be so authenticated.

The tracking device 14 then sends a confirmation signal to the fixture 12 along with the current status (step 130). The confirmation signal may be displayed on the mobile device or via an indicator on the fixture 12. The relative position with respect to the fixture 12, or a global position of the tracking device 14, is then fixed in the armed condition (step 140).

Should a thief disturb the valuable (step 150), which creates motion, movement and potentially light should a bag be opened, the tracking device 14 then sends a notification signal to the fixture 12 (step 160). Upon return of the guest, the guest can be notified by the fixture 12 that motion/movement of his valuable occurred. Alternatively, the guest may be alerted in real time via an app on a smartphone should the fixture 12 be connected through the Internet or other communication medium. The guest can then check his valuables to determine if any item is missing. Alternatively still, multiple fixtures 12 may be utilized to track the tracking device 14 such as should the bag be moved down a hallways with multiple fixtures 12.

The fixture 12 can alternatively or additionally sounds an alarm, show an indication, and/or send an alert to hotel security (step 170). This may also be utilized to generate audits/access logs in the fixture 12 about the motion and movement for later investigation. That is, the open and movement audits may be sequenced with the access events in the fixture 12 along with timestamps to identify, for example, a cleaning crew entry access associated with the open and movement events in a sequence of timestamps. When there is a movement of the valuable, the audit would be logged with the time stamp, access information, and location, which can facilitate identification and location of the valuable. The timestamp will also facilitate investigation of the valuable's movement. One advantage usage with electromechanical locks is that the tagged valuable has to move through the door/lock which can create access, as well as facilitate movement audit trails.

The tracking device 14 can be unarmed in response to a valid and authenticated access event such as return of the owner so that the fixture 12 will unarm the tracking devices 14 when the guest returns to the room. Unarm operation can be made with preferences from guest, where the guest can unarm a few valuables and maintain some armed.

Increased security of valuables minimizes concern of guests when they leave their the hotel rooms. This will also facilitate in tracking and investigating of the valuables. This will increase customer satisfaction with electromechanical locks.
